[axis2] Serialization of Java-Classes

[Benjamin Ernst]

Hi,
I am new to axis2 and I am trying to build a WebService which can handle some complex Datatypes. Is there any Document, that describes Serialization in Axis2?

My Method for the WebService is:

---------------------CODE--------------------------------
/**
     * Gets the first Light found in the desired Room.
     *
     * @return Light located in the Room, if found.
     */
    public Light getLight(Room room) {
        ArrayList<Light> lights = this.ninoRep.getLights();
        for (int i = 0; i < lights.size(); i++) {
            Light l = lights.get(i);
            Room r = l.getisInRoom();
            if (room.equals(r))
                return l;
        }
        return null;
    }
---------------------CODE--------------------------------

Both Classes Room and Light are rather complex. I need these classes, because I want to use them in a Semantic Web Service. But fore that I need a "normal" WS.
Do I have to make custom MessageReceivers for every Class? Or is there an easier, more general way?



An other Problem: After deploying my Service everything is fine, except when I want to get the WSDL-File. Then the following error comes up:

--------------------ERROR--------------------------------
HTTP Status 500 -

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.15 logs.
--------------------ERROR--------------------------------

With the java2WSDL-Tool the WSDL-generation works fine.

Thanks for your help!
